LIGHTING-FIXTURE.

Speciflcationof Letters Patent.

Application filed December 19, 1919. Serial No. 5,091.

To all whom it may concern Be it known that I, WILLIAM E. JEROME, a citizen of the United States, residing at Rockville Center, in the county of Nassau and State of New York, have invented an Improvement in Lighting-Fixtures, of which the following is a s ecification M invention reiiites to lighting fixtures of tlie semi-indirect character employing high efiiciency incandescent lamps, burning at high temperatures whose filaments are exceedingly bright, and its object is to direct the light upward to the ceiling. and from thence over a given area and at the same time to hide the filament from direct View, and blend the light diffused by the translu cent bowl so that strain or injurious eflect upon the eye is entirely avoided.

The details of the invention are hereinafter particularly described.

In the accompanying drawing:

Figure 1 is an elevation partly in section; illustrating a complete fixture embodying my invention.

Fig. 2 is a lan view of the combined re flector and shield detached.

Fig. 3 is aview illustrating the clips used in suspending the translucent bowl, and

Fig. 4 illustrates the reflector and shield made of one piece of material.

Similar reference characters indicate like parts throughout the several views.

10, denotes a translucent bowl which may be supported by any suitable hangers, but I prefer to employ clips 11, formed of a single piece of flat metal bent into the shape shown most clearly in Fi 3, which fit over and under the flange oft e bowl with one end bent downwardly and bearing against the inner surface of the bowl, there being a loo or eye 12, bent upwardly above the rim 0 the bowl to receive one end of the chains 13, the 1 other ends of these chains being connected to the socket cover 14, the incandescent lamp 15, being screwed into the end of a socket within said cover.

The socket cover is suspended by a chain ,16, depending from a canopy 17, which is secure to a ceiling in any suitable manner.

The conductor wires (not shown) pass through the cano y 17, are looped through the links of the 0 sin 16, and connect with the lamp socket inside the cover 14, in the ordinary manner.

18, indicates a frusto-conical reflector flared upwardly and outwardly and pro vided with a frusto-conical skirt or shield 19, flared downwardly, and outwardly, but preferably at a lesser degreee of outward flare than the reflector.

The reflector andshield may be made integral as shown in Fig 1 and of any suitable material, but I prefer to make them of metal and separately, secured together by rivets 20, as shown in Fig. 1, there being provided an annular flange 21, at the bottom of the reflector which fits within the upper end of the shield and through which the rivets pass.

22. denotes a plurality of spaced fingers, three of these being preferably employed), which are formed of a narrow flat strip of metal, or other suitable material, one end of each of which is secured to the inside of the reflector 18, at its lower part by rivets 23, and extends therefrom in a horizontal line a distance corresponding to the length between the outer edge of the rim and inner surface of the translucent bowl 10, the free end of each finger being bent downwardly at ri ht angles to bear against the inner surface 0? the bowl as shown in Fig. 1. It will thus be seen that the combined reflector and shield is sup ported by the translucent bowl 10, the spaced fingers 22, resting upon the top of the rim of the bowl, while their downwardly bent ends bear against the inner surface of the bowl and prevent any lateral movement of the reflector and shield:

The combined reflector and shield may be readily applied to or detached from the fixture without disturbin any parts thereof.

In placing it u on t e fixture it is passed over the bowl slightly tipped to one side sufliciently to allow the fingers to clear the rim of the bowl until the are in a position to be seated thereon, while inmemovin it from the fixture it is only necessary to li it off the rim and tip it in the same manner as when ap lyin it.

It has been 'ound in practice that the best lighting efl'ect is obtained when the lam is hung in therelative position shown in ig. 1, that is above the translucent bowl and surroundedby the reflector. In this osition the filament is entirely hidden rom Patented Aug. 24, 1920.

view, while the light is directed by the reupon the eyes of the beholder; in fact, when the inner surface of the shield is coated with white paint or enamel, the light is so blended that the translucent bowl is scarcely perceptible.

It will be readily understood that the exterior brightness of the light diflusing bowl 10, may be increased or modified, by simply lowering the lamp more or less.

I claim as my invention:

1. A lighting fixture comprising an upwardly flaring reflector and a downwardly flaring reflector joined at theirsmaller ends to form a single reflecting body, a translucent bowl and incandescent lamp around which the reflecting body is supported in such manner that the bowl is within the lower reflector and the lamp within the upper reflector.

2. A lighting fixture comprising a frustoconical upwardly flaring reflector and a frusto conical downwardly flaring reflector joined at their smaller ends to form a single reflecting body, a translucent bowl and source of light around which the reflecting body is supported in such manner that the bowl is within the lower reflector and the source of light within the upper reflector.

3. In a lighting fixture, the combination of a lamp, a bowl, means for suspending the same, a frusto-conical reflector upwardly flared and a depending frusto-conical shield outwardly flared, and means for supporting the same upon the bowl.

4. In a li hting fixture, the combination of a lamp an socket therefor, a socket cover, means for suspending the same, a bowl, means for supporting the same in predetermined relation to the lamp, a frusto-conical reflector upwardly flared, a dependingfrusto-conical shield outwardly flared, and a plurality of attached fingers bearing upon the rim of the bowl and supporting the reflector and shield.

5. In a lighting fixture, the combination of a lamp and socket therefor, a socket cover, means for suspending the same, a bowl, a plurality of clips, each formed of one piece of metal bent into a shape to fit over and under the flange of the bowl with one end extending downwardly into the bowl against its inner surface and having an upwardly turned loop intermediate its ends, chains connected at one end to the said loops and at their other ends to the socket cover, a frustoconical reflector upwardly flared, a de ending frusto-conical shield outwardly flhred, and a plurality of attached fingers bearing upon the rim of the bowl and supporting the reflector and shield.

Signed by me this 21 day of November 1919.
